The son of a Christian minister and president of Saitō High School's Holy Student Council. He has curly blonde hair and as the series progresses, he grows it long and keeps it in a ponytail. Though he has no spiritual powers aside of seeing ghosts, Haruto is entrusted with the seven badges of the school spirits and summons them as necessary. He hates his job and dealing with ghosts, but his attempts to resign or transfer schools are constantly sabotaged by the Chairman. His dream is to spend one day attending classes, though his fellow student council members enjoy slacking off. With the exception of Episode 6, every episode ends with him saying "Oh my God!"

In the manga, while Haruto still thinks he doesn't really fit in the Council in his own words, he's noticeably more mature, reliable and level-headed than his anime incarnation, and gets along somewhat better with the spirits.
